If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

Answer:
x = -4/3 x = 1/2
x=0 x = -3/4
Step-by-step explanation:
(3x+4) (2x-1)=0
Using the zero product property
3x+4 = 0 2x-1 =0
3x= -4 2x= 1
x = -4/3 x = 1/2
x (4x+3) =0
Using the zero product property
x = 0 4x+3 = 0
x=0 4x=-3
x=0 x = -3/4
